  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 2. Dynamic Risk Management in Air Traffic Management System Failures

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Nick Lowth; [2024]
    Keywords : Air Traffic Control; Uncertainty; Risk Management; Air Traffic Management; Resilience; Emergence; Trade-offs; FLMU06; Social Sciences;

    Abstract : Context This research looks at managing uncertainty and recovery processes following failure of a sociotechnical system. The provision of Air Traffic Services (ATS) is an essential service that must continue to function supporting at a minimum; medical flights, search and rescue operations, humanitarian aid, State and military flights (as demonstrated during the recent global pandemic).

  4. 3. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  5. 4. Second Life Applications for Degraded EV Batteries : Evaluating Benefits Basedon Remaining Useful Life and Battery Configurations

    University essay from Linköpings universitet/Fordonssystem

    Author : Sandberg Elis; [2023]
    Keywords : ;

    Abstract : This thesis explores the potential of second-life electric vehicle batteries, which are no longer suitable for electro-mobility, to provide energy storage solutions. The study iden- tifies two potential applications for second-life batteries: charging stations and residential PV energy storage systems. READ MORE

  6. 5. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Karnsinee Viriyayudhakorn; [2023]
    Keywords : human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Abstract : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. READ MORE
